Oyster Reef Restoration
Oyster reef restoration refers to the process of rebuilding or restoring of oyster reefs all over the globe. Over time, oysters have been negatively affected by environmental change, such as harmful fishing techniques, over harvesting, water pollution, and other factors. The results of these factors have been disease and ultimately, a large decline in the global population of oysters and the prevalence and sustainability of oyster reefs. Apart from the ecological importance of oyster reefs, oyster farming is an important industry, particularly in coastal areas. Both artificial materials and natural components have been used to rebuild the reefs in an attempt to regenerate the oyster population thus fostering the reformation of reefs. Ecosystem The first stage in an oyster’s life cycle is the free-swimming larval stage. After about three weeks, the larva attaches to a hard substrate—surface area to attach to—such as prop roots, dock pilings, natural rock, and other oyster ...

Indicator Species
A bioindicator is any species (an indicator species) or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water body, water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollution, pollutants in the ecosystem and about how long a problem may have been present, which Water pollution#Measurement, physical and chemical testing cannot. A biological monitor or biomonitor is an organism that provides quantitative property, quantitative information on the quality of Environment (biophysical), the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and can also be used in an attempt to provide additional inform ...

Aquaculture
Aquaculture (less commonly spelled aquiculture), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus). Aquaculture involves cultivating freshwater, brackish water and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture, commonly known as marine farming, refers specifically to aquaculture practiced in seawater habitats and lagoons, opposed to in freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food. Aquaculture can also be defined as the breeding, growing, and harvesting of fish and other aquatic plants, also known as farming in water. It is an environmental source of food and commercial product which help to improve healthier habitats and used to recon ...

Texas A&M-Corpus Christi
Texas (, ; Spanish: ''Texas'', ''Tejas'') is a state in the South Central region of the United States. At 268,596 square miles (695,662 km2), and with more than 29.1 million residents in 2020, it is the second-largest U.S. state by both area (after Alaska) and population (after California). Texas shares borders with the states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south and southwest; and has a coastline with the Gulf of Mexico to the southeast. Houston is the most populous city in Texas and the fourth-largest in the U.S., while San Antonio is the second most populous in the state and seventh-largest in the U.S. Dallas–Fort Worth and Greater Houston are, respectively, the fourth- and fifth-largest metropolitan statistical areas in the country. Other major cities include Austin, the second most populous state capital in t ...

Ecotourism
Ecotourism is a form of tourism involving responsible travel (using sustainable transport) to natural areas, conserving the environment, and improving the well-being of the local people. Its purpose may be to educate the traveler, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures and for human rights. Since the 1980s, ecotourism has been considered a critical endeavor by environmentalists, so that future generations may experience destinations relatively untouched by human intervention. Ecotourism may focus on educating travelers on local environments and natural surroundings with an eye to ecological conservation. Some include in the definition of ecotourism the effort to produce economic opportunities that make conservation of natural resources financially possible. Generally, ecotourism deals with interaction with biotic components of the natura ...

Foundation Species
In ecology, the foundation species are species that have a strong role in structuring a community. A foundation species can occupy any trophic level in a food web (i.e., they can be primary producers, herbivores or predators). The term was coined by Paul K. Dayton in 1972,Dayton, P. K. 1972Toward an understanding of community resilience and the potential effects of enrichments to the benthos at McMurdo Sound, Antarctica pp. 81–96 in Proceedings of the Colloquium on Conservation Problems Allen Press, Lawrence, Kansas. who applied it to certain members of marine invertebrate and algae communities. It was clear from studies in several locations that there were a small handful of species whose activities had a disproportionate effect on the rest of the marine community and they were therefore key to the resilience of the community. Dayton’s view was that focusing on foundation species would allow for a simplified approach to more rapidly understand how a community as a whole would ...

Eastern Oyster
The eastern oyster (''Crassostrea virginica'')—also called the Atlantic oyster, American oyster, or East Coast oyster—is a species of true oyster native to eastern North and South America. Other names in local or culinary use include the Wellfleet oyster, Virginia oyster, Malpeque oyster, Blue Point oyster, Chesapeake Bay oyster, and Apalachicola oyster. ''C. virginica'' ranges from northern New Brunswick through parts of the West Indies and south to Brazil. It is farmed in all of the Maritime provinces of Canada and all Eastern Seaboard and Gulf states of the United States, as well as Puget Sound, Washington, where it is known as the Totten Inlet Virginica. It was introduced to the Hawaiian Islands in the nineteenth century and is common in Pearl Harbor. The eastern oyster is an important commercial species. Its distribution has been affected by habitat change; less than 1% of the population present when the first European colonists arrived is thought to remain in the Ch ...

Oyster Reef
The term ''oyster reef'' refers to dense aggregations of oysters that form large colonial communities. Because oyster larvae need to settle on hard substrates, new oyster reefs may form on stone or other hard marine debris. Eventually the oyster reef will propagate by spat settling on the shells of older or nonliving oysters. The dense aggregations of oysters are often referred to as an oyster reef, oyster bed, oyster bank, oyster bottom, or oyster bar interchangeably. These terms are not well defined and often regionally restricted. Degradation of oyster reefs Oyster reefs were once common in estuaries around the world. Within the last century there have been significant declines in the extent and condition of oyster reefs globally, driven by overharvesting of oysters for food provision and lime production, and coastal degradation. In the United States ''Crassostrea virginica'', the eastern oyster, was a major reef builder in the Chesapeake Bay until the late 19th century. B ...

Oyster Shell Recycling
Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters are in the superfamily Ostreoidea. Some types of oysters are commonly consumed (cooked or raw), and in some locales are regarded as a delicacy. Some types of pearl oysters are harvested for the pearl produced within the mantle. Windowpane oysters are harvested for their translucent shells, which are used to make various kinds of decorative objects. Etymology The word ''oyster'' comes from Old French , and first appeared in English during the 14th century. The French derived from the Latin , the feminine form of , which is the latinisation of the Ancient Greek () 'oyster'. Compare () 'bone'. Types True oysters True oysters are members of the family Ostreidae. This family includes the edible oysters, which mainly belong to ...

Bonamia Ostreae
''Bonamia ostreae'' is a parasitic Rhizaria in the phylum Haplosporidia that can cause lethal infections in shellfish, particularly the European flat oyster, ''Ostrea edulis''. Infection in oysters rarely results in clinical signs of disease and often the only indication of the infection is increased mortality. The Australian flat oyster, ''Ostrea angasi'', has been infected with two similar ''Bonamia'' parasites, ''Bonamia exitiosa'' and ''B. roughleyi''. Pathology The cells of ''Bonamia ostreae'' measure 2-3 µm in diameter and are found within the haemocytes of the oyster. Lesions occur with focal infiltration of the haemocytes within the connective tissue of the mantle and gills, and in the vascular sinuses near the digestive gland, intestine and stomach. Infection seems to be correlated to haemocyte destruction and diapedesis. Epidemiology A study in the Netherlands of the epidemiology of European flat oysters, ''Ostrea edulis'', infected with ''Bonamia ostreae'' show ...
